A judge has blocked Iowa State University from releasing documents about
food safety research conducted for the beef-processing company that
makes the product dubbed "pink slime" by critics.

District Judge Dale Ruigh ruled last month that releasing the records
would damage Beef Products, Inc. by revealing information about its
proprietary food-processing techniques. Releasing them also would
eliminate revenue that Iowa State laboratories receive from companies,
who would go elsewhere for testing if they feared results were public
records, he said.

Also, the people might be able to tell what other kinds of materials that are similar to pink slime are put into all foods. Probably, if people knew what was going into all food, everyone would want to go back to growing their own foods, and the whole food industry would collapse.
